What's Wrong?

When terminal application (shell) is set to GitBash (C:\Program FIles\Git\bin\bash.exe) in Webstorm:

Claude code cannot see any available IDEs:

as well as Claude plugin cannot find Claude code:

What Should Happen?

Claude code should find IDE, claude plugin should find claude code.
